Conductive PCD Holder with Sealed EMI Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an improved container that effectively blocks electromagnetic interference (EMI) and prevents personal communication devices (PCDs) from making sounds or vibrating in sensitive environments, such as courtrooms, meeting rooms, and vehicles, where disruptions need to be minimized.
Innovation Solution
The development of a data transfer blocking container or holder made from conductive materials like metal, plastic, or synthetic materials with integrated conductive layers, which encases PCDs to prevent data transmission and reception, providing physical protection and drop resistance, and can be designed for single or multiple devices with adjustable sizes and security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PCD holder is made from conductive materials to block electromagnetic interference, then data signal blocking effectiveness is improved, but manufacturing complexity increases due to the need for conductive coatings or laminates
Solution Approach 1:
The holder combines non-conductive base materials (plastic or synthetic) with conductive coatings or laminates to achieve both structural integrity and electromagnetic interference blocking. This composite approach allows the holder to block data signals while maintaining ease of manufacturing through standard molding processes followed by coating applications.
2Strength
If the holder is made rigid or semi-rigid to provide physical protection, then drop resistance and impact protection are improved, but device complexity increases due to additional protective layers
Solution Approach 1:
The holder merges multiple functions into a single integrated structure: the rigid or semi-rigid walls provide both physical protection against drops and impact, while simultaneously serving as the EMI shielding barrier. The conductive coating is applied directly to the inner surface of these protective walls, combining structural support and signal blocking in one component rather than adding separate layers.
3Reliability
If the holder completely encloses the PCD to block all signals, then data transmission blocking is improved, but ease of operation decreases due to restricted access
Solution Approach 1:
The holder incorporates a movable lid or door mechanism that allows dynamic switching between enclosed and accessible states. When closed, the lid maintains complete signal blocking by maintaining contact with conductive sealing surfaces. When opened, it provides full access to the PCD for insertion, removal, or charging, allowing the holder to adapt its degree of enclosure based on operational needs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents PCDs from receiving or emitting data signals, ensuring they remain silent and non-disruptive, while also offering physical protection and security features, making it suitable for various environments and applications.
Implementation Method 1
The walls are either formed of or have affixed a metal shell that encloses the PCD so that data (e.g., phone, email or text data) cannot be transmitted from or be received by the PCD

AI summary
A personal communication device (“PCD”) holder includes: (i) a male housing component including a capped end and a first tubular wall extending from the capped end to a male mating end, the male housing component data signal blocking; (ii) a female housing component including a capped end and a second tubular wall extending from the capped end to a female mating end, the female housing component data signal blocking; (iii) a first liner material conforming to an inner surface of the male housing component; (iv) a second liner material conforming to an inner surface of the female housing component; and (v) a data signal blocking gasket positioned to reside between an exposed outer surface of the data signal blocking material of the male mating end and the exposed inner surface of the data signal blocking material of the female mating end.
